No issues with getting sick. We roast the night before, refrigerate overnight. Then put in ziploc baggies for the ride. So perhaps they are 3 hours on the ride before consumption and we toss anything that doesn't get eaten. My digestive system can't handle power bars, luna bars et al. I can eat about 1/4 of a cliff bar at best so am always open to ideas on easy to pack, high energy food for long rides.
